Sorry about that but unless you identify what is causing the problem with xorg things may to get worse.
There is a pending Ubuntu-Mate 16.04 update to mesa 17.07 that may also cause you the same problems .

Option 3 for installing Ubuntu-Mate 16.04
A usb .img that can be booted and copied using dd to a harddrive partition .
Image is compressed as 7z so needs to be extracted before writing .
has a username of Amigaone with password of amigaone .
Once installed you will need to update as it uses the first version of the Ubuntu-Mate .
no live user on this one.
should upload a newer version but it takes about 12 hours with my connection's upload speed .

I tried "the option 3 this morning"... Downloading the package failed after loading about 2.5 GB of the 2.6 GB total! Resuming the transfer was not possible, Firefox had deleted the file automatically. Cannot try again from the start, my data account went now too low.

This really made my week - everything I have tried to do with Amiga Linuxes this week has failed, just everything... :-/

Ubuntu 16.04.2 with proposed Mesa 17.07 .

For Radon Southern Island cards you will need a new xorg.conf for the fbdev device.

I got this pacakage finally downloaded, and had the opportunity to test this 'option 3'. The unpacking was also succesful, and I copied with dd the image on a parttion I created on a USB stick. But when I checked the partition with GParted, it reported the filesystem was unknown.... Thus also booting from that partition is impossible. What went wrong? Should the partition have certain attributres before copying the image on it, or should it be 'dd'ed on the disk unit's 'root level' and not on a ready made partition? I don't have currently any empty USB unit so I cannot now test myself...

Did you create a Linux partition with an ext4 file system with GParted?

For example:

I created it with GParted, but I chose ext2... Is that important?

OK, I understand what the problem is. You copied the whole img with partitions included to an empty partition. You can't copy several partitions to an empty partition. This doesn't work.

Please look in the image with fdisk -l

Code: Select all

fdisk -l Ubuntu-Mate_16.04.img

Code: Select all

Disk Ubuntu-Mate_16.04.img: 7,2 GiB, 7747397632 bytes, 15131636 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x3a30f5e7

Device                 Boot    Start      End  Sectors  Size Id Type
Ubuntu-Mate_16.04.img1          2048   206847   204800  100M  6 FAT16
Ubuntu-Mate_16.04.img2        206848 14925823 14718976    7G 83 Linux
Ubuntu-Mate_16.04.img3      14925824 15130623   204800  100M 83 Linux
Do you understand what the problem is? This image was produced for a whole empty stick.

But you can mount a partition in an image and after that copy it with dd to a partition on your X5000. ;-)

Please install kpartx:

Code: Select all

apt-get install kpartx

Code: Select all

kpartx -l Ubuntu-Mate_16.04.img -a

Code: Select all

kpartx -l Ubuntu-Mate_16.04.img

Code: Select all

loop0p1 : 0 204800 /dev/loop0 2048
loop0p2 : 0 14718976 /dev/loop0 206848
loop0p3 : 0 204800 /dev/loop0 14925824
loop0p2 is the ubuntu MATE 16.04.2 LTS root partition.

Code: Select all

mount /dev/mapper/loop0p2 /mnt/ -o loop,ro
Another option without kpartx:

Code: Select all

sfdisk -d Ubuntu-Mate_16.04.img

Code: Select all

label: dos
label-id: 0x3a30f5e7
device: Ubuntu-Mate_16.04.img
unit: sectors

Ubuntu-Mate_16.04.img1 : start=        2048, size=      204800, type=6
Ubuntu-Mate_16.04.img2 : start=      206848, size=    14718976, type=83
Ubuntu-Mate_16.04.img3 : start=    14925824, size=      204800, type=83

Code: Select all

echo $((206848 * 512)) $((14718976 * 512))
Result: 105906176 7536115712

Then:

Code: Select all

mount -o loop,offset=105906176,sizelimit=7536115712 Ubuntu-Mate_16.04.img /mnt
Please try it.

Yes... :-) That's what I suspected, but had no 'tools' to verify that. Thanks!

I think I succeeded now to mount the partition with the second option you gave (without kpartx). At least there were no error messages...

Now, what is the 'name' (and path) of this mounted partion and in what format should I give it to dd? I am not familiar with this loop concept...

Please post the output of df -h after you mounted the partition.

I'm doing it on a different machine so I will not retype the full output, but I suppose it is this line which is involved:

/dev/loop0 6,9G 5,3G 1,3G 82% /mnt
